閱讀下面短文并回答問(wèn)題，然后將答案寫(xiě)到答題卡相應(yīng)的位置上（請(qǐng)注意問(wèn)題后的詞數(shù)要求）。
[1]Oops! In your rush to get to school, you drop a piece of toast on the floor. Do you throw it away or decide it’s still OK to eat? If you’re like most people, you eat it. Maybe you follow the “5-second rule”, which claims foods are safe to eat, if you pick them up within 5 seconds of dropping them. But you might want to think again. Scientists now say that 5 seconds are all it takes for foods to become contaminated with enough bacteria to make you sick.
[2]Bacteria can cause many kinds of illnesses. Some kinds of bacteria can grow on food. If we eat foods on which these bacteria are growing, we can become sick. One of these food-borne bacteria is Salmonella. It makes 1.4 million people sick every year. Earlier this year, 370 people became sick after eating peanut butter that had been contaminated with Salmonella at the manufacturing factory. Salmonella are often found in raw eggs and chicken. Cooking kills these bacteria, which is why it is so important to cook eggs, chicken, and other foods carefully.
[3]Being a good housekeeper is another good way to prevent infection. If household surfaces aren’t washed thoroughly, they can support Salmonella for weeks. A team of scientists at Clemson University in South Carolina have tested the 5-second rule, using sandwich ingredients. First, they placed a known amount of Salmonella cells on three surfaces: wood, tile, and carpet. They then placed a slice of bread and a slice of bologna(博洛尼亞大紅腸) on each surface for 5, 30, or 60 seconds. After just 5 seconds, both the bread and bologna picked up enough bacteria to make you sick.
[4]So forget the 5-second rule. If your toast lands on the floor, throw it away. Stick a fresh slice of bread in the toaster. And this time, be careful not to drop it!

Answer 1

小題1:If you pick food up within 5seconds of dropping them, they are safe to eat.
小題2:Because cooking kills bacteria.
小題3:Don’t eat food that has dropped on the floor./ being a good housekeeper.
小題4:To find out how long it takes these bacteria to attach to food.
小題5:Negative.

試題分析：“五秒理論”認(rèn)為，食物掉落地上的五秒之內(nèi)仍然是可以撿起來(lái)吃的。然而，這種說(shuō)法得到了科學(xué)家的反對(duì)。在五秒的時(shí)間里，細(xì)菌就已經(jīng)充滿了掉落的食物，掉落地上的食物是不能食用的。
小題1:根據(jù)第一段“Maybe you follow the “5-second rule”, which claims foods are safe to eat, if you pick them up within 5 seconds of dropping them.”可知，食物在掉落的五秒之內(nèi)被撿起時(shí)，食物還是安全的，故填I(lǐng)f you pick food up within 5seconds of dropping them, they are safe to eat.
小題2:根據(jù)第二段“Bacteria can cause many kinds of illnesses. ...Cooking kills these bacteria,”可知，通過(guò)燒煮能夠殺死食物里的細(xì)菌，故填Because cooking kills bacteria.
小題3:根據(jù)最后一段“So forget the 5-second rule.”可知，第一段提到的“五秒理論”并不科學(xué)，掉到地上的食物不能再食用，故填Don’t eat food that has dropped on the floor./ being a good housekeeper.
小題4:根據(jù)第三段“After just 5 seconds, both the bread and bologna picked up enough bacteria to make you sick.”可知，食物五秒鐘就充滿了細(xì)菌，這個(gè)實(shí)驗(yàn)的目的是為了驗(yàn)證食物滋生細(xì)菌需要多長(zhǎng)時(shí)間，故填To find out how long it takes these bacteria to attach to food.
小題5:根據(jù)第一段“Scientists now say that 5 seconds are all it takes for foods to become contaminated with enough bacteria to make you sick.”和第四段“So forget the 5-second rule.”可知，作者對(duì)“五秒理論”持否定的態(tài)度，故填Negative.
